I am a Pentax 645Z shooter and tried a P645 a few years ago for the film experience. For me, if going for a legacy camera, I'd perfer one that is totally manual. I had some issues with the motorized film advance, so returned the camera. From FB groups, I know that are many wedding photographers that use the P645. So, my version may have been a lemon. I've own a Mamiya C330S TLR for over 30 years. If I were recommending a camera for the first MF film experience, I'd recommend the C330. It may be a little cheaper than the P645 too.
